Description

本発明は、カード型記録媒体のコネクタ、フラットケーブル端子のコネクタ等、扁平な形状を有する薄型コネクタに関する。また、本発明でいう薄型挿入体とは、カード型記録媒体やフラットケーブル端子である。   The present invention relates to a thin connector having a flat shape, such as a connector of a card type recording medium, a connector of a flat cable terminal or the like. Further, the thin insert referred to in the present invention is a card-type recording medium or a flat cable terminal.

近年の電子デバイスの小型化に伴い、カード型の記録媒体や薄型のフラットケーブル端子が広く用いられている。カード型記録媒体やフラットケーブル端子等の薄型挿入体を用いる際、薄型挿入体がコネクタに正しく挿入されない状態で機器に通電してしまうと、記録媒体中のデータを破損してしまったり機器の故障の原因となったりする。そこで、薄型挿入体が正しく挿入されたか否かを、薄型挿入体の挿入に伴って変形するカンチレバーの導通・非導通で検出する検出機構を備えた薄型コネクタが知られている（特許文献１参照）。この薄型コネクタに薄型挿入体が挿入されると、薄型挿入体がカンチレバーを押圧し、カンチレバーが弾性変形して導通・非導通の状態が変化する。薄型コネクタに内蔵された検出機構は、このカンチレバーの導通状態の変化を検出して薄型挿入体の挿入を検出する。   With recent downsizing of electronic devices, card-type recording media and thin flat cable terminals are widely used. When using a thin insert such as a card-type recording medium or flat cable terminal, if the device is energized without the thin insert being correctly inserted into the connector, the data in the recording medium may be damaged or the device may malfunction. It may cause. Therefore, a thin connector having a detection mechanism for detecting whether or not the thin insert has been correctly inserted by detecting whether the cantilever deforms as the thin insert is inserted is known (see Patent Document 1). ). When the thin insert is inserted into the thin connector, the thin insert presses the cantilever, and the cantilever is elastically deformed to change the conductive / non-conductive state. A detection mechanism built in the thin connector detects the insertion of the thin insert by detecting a change in the conduction state of the cantilever.

ところで、このような検出機構を備えた薄型コネクタを機器の基板上に表面実装するため、例えばはんだリフロー方式で薄型コネクタを基板に取り付ける時には、基板に取り付けられるカンチレバーの端子部からはんだが上がってきてしまうことがある。そして、上がってきたはんだがカンチレバー本体に付着すると、カンチレバーのばね定数の変化に伴って所定値以上の応力がカンチレバーに負荷され、その結果、カンチレバーが早期に破損してしまう可能性があった。このはんだ上がりを防止するための技術として、特許文献２や特許文献３に記載の技術が知られている。   By the way, in order to surface-mount a thin connector having such a detection mechanism on a substrate of a device, for example, when the thin connector is attached to the substrate by a solder reflow method, the solder rises from the terminal portion of the cantilever attached to the substrate. May end up. When the solder that has risen adheres to the cantilever body, a stress of a predetermined value or more is applied to the cantilever as the spring constant of the cantilever changes, and as a result, the cantilever may be damaged early. As techniques for preventing the solder from rising, techniques described in Patent Document 2 and Patent Document 3 are known.

特許文献２には、電子部材の接点部位にはんだとのぬれ性の低い樹脂やセラミックスを塗布してはんだ上がり防止帯を形成する方法が記載されている。
また、特許文献３には、はんだ付けされる端子部において、ニッケル下地層の上にはんだがのりやすい金めっき層を設けてはんだ付け領域を形成し、更にこのはんだ付け領域の上部にレーザー光線を照射してはんだとのぬれ性の悪いニッケル金合金を形成してはんだ這い上がり防止領域を形成する方法が知られている。 Patent Document 2 describes a method of forming a solder rising prevention band by applying a resin or ceramic having low wettability with solder to a contact portion of an electronic member.
Further, in Patent Document 3, a soldering region is formed by providing a gold plating layer on which a solder is easily applied on a nickel base layer in a terminal portion to be soldered, and further, a laser beam is irradiated on the upper portion of the soldering region. Then, a method is known in which a nickel gold alloy having poor wettability with solder is formed to form a solder creep-up prevention region.

しかしながら、上述の方法は樹脂等を塗布したり、めっき加工とレーザー加工を施したりするので、工数が嵩んで製造コストが上昇するという問題があった。
そこで本発明は簡単な構成ではんだ上がりを防止して、長い寿命を有する挿入検出機構を備えた薄型コネクタを安価に提供することを目的とする。 However, since the above-described method applies a resin or the like, or performs a plating process and a laser process, there is a problem that man-hours increase and the manufacturing cost increases.

Therefore, heat conduction from the terminal portion to the supported portion during soldering is suppressed by the reduced cross-sectional area portion, and an increase in the temperature of the supported portion can be suppressed. Therefore, even if the terminal portion is heated to a temperature at which the solder adheres, the supported portion is not heated to a temperature at which the solder adheres, so that the solder can be prevented from rising to the supported portion. Since the 2nd elastic piece which does not want to make solder adhere is provided in the side different from the terminal part of a supported part, it can prevent reliably that solder adheres to the 2nd elastic piece. Providing a low-profile connector with an insertion detection mechanism having a long life can be achieved by providing a simple configuration in which a reduced cross-sectional area is provided between the supported portion and the terminal portion in this way. Can do.

次に、ハウジング２の内部に設けられるコネクタ端子部材３、第１端子部材４、第２端子部材５について説明する。図２は、これらの部材を説明するためにカバー２２を取り外して特に第１端子部材４、第２端子部材５を拡大して示す要部拡大図である。   Next, the connector terminal member 3, the first terminal member 4, and the second terminal member 5 provided in the housing 2 will be described. FIG. 2 is an enlarged view of a main part showing the first terminal member 4 and the second terminal member 5 in an enlarged manner by removing the cover 22 in order to explain these members.

図２の如くコネクタ端子部材３はハウジング２の基板６側に設けられる。コネクタ端子部材３は、例えば金属の打ち抜きおよびプレス加工により形成される導電性の部材である。この端子部材は、後述する第１端子部材４と第２端子部材の弾性変形による通電状態の変化を検出して、薄型挿入体７の挿入状態を検出するためのものである。コネクタ端子部材３は、複数の挿入体側端子３１と、各々の挿入体側端子３１と接続され薄型コネクタ１の外部に接続される複数の外部接続用端子３２とを有する。挿入体側端子３１は、挿入空間に挿入される薄型挿入体７の端子と対応するように配置され、基体２１からカバー２の天壁２２に向かって延びて薄型挿入体７の端子と弾性接触する。   As shown in FIG. 2, the connector terminal member 3 is provided on the substrate 6 side of the housing 2. The connector terminal member 3 is a conductive member formed by, for example, metal punching and pressing. This terminal member is for detecting the insertion state of the thin insert 7 by detecting a change in energization state due to elastic deformation of the first terminal member 4 and the second terminal member, which will be described later. The connector terminal member 3 includes a plurality of insertion body side terminals 31 and a plurality of external connection terminals 32 connected to the insertion body side terminals 31 and connected to the outside of the thin connector 1. The insertion body side terminal 31 is disposed so as to correspond to the terminal of the thin insertion body 7 to be inserted into the insertion space, and extends from the base body 21 toward the top wall 22 of the cover 2 to elastically contact the terminal of the thin insertion body 7. .

第１端子部材４は、例えば金属の打ち抜きおよびプレス加工により形成される導電性の細長い板状部材である。第１端子部材４は薄型挿入体７の挿入方向に沿ってハウジング２の側壁に設けられ、後述する第２端子部材５よりも挿入口２０側に配置される。   The first terminal member 4 is a conductive elongated plate-like member formed by, for example, metal punching and pressing. The 1st terminal member 4 is provided in the side wall of the housing 2 along the insertion direction of the thin insertion body 7, and is arrange | positioned at the insertion port 20 side rather than the 2nd terminal member 5 mentioned later.

第１端子部材４は、第１支持部２１Ａで支持される第１被支持部４２と、第１被支持部４２からカバー２２の後壁２２ｒに延びる第１弾性片４３と、基板６と電気的に接続され前記第１被支持部４２から第１弾性片４３と異なる基板６の厚み方向に延びる第１端子部４１と、第１弾性片４３の先端に設けられ薄型挿入体７と当接する当接部４４とを有する。第１端子部４１は第１弾性片４３よりも挿入口２０側に位置する。第１弾性片４３は薄型挿入体７の挿入方向に沿って延び、第１被支持部４２を中心に基板６と平行な方向に弾性変形可能である。当接部４４は挿入空間の内側に凸となるように湾曲しており、薄型挿入体７が挿入されると、薄型挿入体７は湾曲面に沿って滑らかに接触する。   The first terminal member 4 includes a first supported portion 42 supported by the first supporting portion 21A, a first elastic piece 43 extending from the first supported portion 42 to the rear wall 22r of the cover 22, the substrate 6, and the electric Connected to the first terminal portion 41 extending from the first supported portion 42 in the thickness direction of the substrate 6 different from the first elastic piece 43, and provided at the tip of the first elastic piece 43 to contact the thin insert 7.

The first elastic piece 43 extends along the insertion direction of the thin insert 7 and can be elastically deformed in a direction parallel to the substrate 6 around the first supported portion 42. The contact portion 44 is curved so as to be convex toward the inside of the insertion space, and when the thin insert 7 is inserted, the thin insert 7 smoothly contacts along the curved surface.

第１端子部４１と第１被支持部４２は挿入された薄型挿入体７と干渉しない位置に配置されるが、第１弾性片４３と当接部４４は薄型挿入体７が挿入されたときに薄型挿入体７と干渉する位置に配置される。ゆえに、薄型挿入体７が挿入空間に挿入されると、まず薄型挿入体７の先端が第１弾性片４３に当接した後、薄型挿入体７の挿入に伴って薄型挿入体７の先端は第１弾性片４３に摺接し、やがて当接部４４に当接する。薄型挿入体７が完全に挿入空間に挿入された状態では、薄型挿入体７の側面が当接部４４を当接することになる。   The first terminal portion 41 and the first supported portion 42 are arranged at positions that do not interfere with the inserted thin insert 7, but the first elastic piece 43 and the contact portion 44 are when the thin insert 7 is inserted. Are disposed at positions that interfere with the thin insert 7. Therefore, when the thin insert 7 is inserted into the insertion space, the tip of the thin insert 7 first comes into contact with the first elastic piece 43 and then the tip of the thin insert 7 is inserted along with the insertion of the thin insert 7. It comes into sliding contact with the first elastic piece 43 and eventually comes into contact with the contact portion 44. In a state where the thin insert 7 is completely inserted into the insertion space, the side surface of the thin insert 7 comes into contact with the contact portion 44.

The second terminal member 5 includes a second supported portion 52 supported by the second support portion 21 </ b> B, a bent portion 53 extending from the second supported portion 52, and a second extending from the bent portion 53 toward the insertion port 20. The elastic piece 54 includes a second terminal portion 51 that is electrically connected to the substrate 6 and extends from the second supported portion 52 in the thickness direction of the substrate 6, which is different from the second elastic piece 54. The second elastic piece 54 of the second terminal member 5 is arranged to face the first elastic piece 43 of the first terminal member 4, and when the thin insert 7 is inserted into the insertion space, the first elastic piece 43 It contacts the second elastic piece 54.

第１弾性片４３の押圧付勢力により第２弾性片５４が挿入空間の外側に変位した時、第２弾性片５４が常に一定の圧力で第１弾性片４３と接触するように、第２弾性片５４のばね定数が設定される。具体的には、第２端子部材５の弾性率を考慮して第２被支持部５２から連続する屈曲部５３と第２弾性片５４の長さ、厚み、幅を設定する。   When the second elastic piece 54 is displaced outside the insertion space by the pressing biasing force of the first elastic piece 43, the second elastic piece 54 is always in contact with the first elastic piece 43 with a constant pressure. The spring constant of the piece 54 is set. Specifically, the length, thickness, and width of the bent portion 53 and the second elastic piece 54 that are continuous from the second supported portion 52 are set in consideration of the elastic modulus of the second terminal member 5.

第２端子部材５の第２被支持部５２はカバー２２の後壁２２ｒと平行に延び、第２弾性片５４は薄型挿入体７の挿入方向に沿って延びている。屈曲部５３は略９０度屈曲しており、第２被支持部５２と第２弾性片５４を接続する。また、屈曲部５３は、第２支持部２１Ｂから屈曲部５３側に延びる角部２１Ｃ（弾性変形許容部）により隙間を介して囲まれる。角部２１Ｃは基体２１から上方に突出する一対の突出部であり、一対の突出部の内壁は屈曲部５３の形状に合わせた形状である。角部２１Ｃの一対の突出部は、第２弾性片５４の弾性変形を許容するように屈曲部５３の可動範囲よりも大きな隙間を有して向かい合う。
なお、第２端子部材５は第２支持部材２１Bに支持されているが、第２端子部材５に荷重がかけられても基板６から外れないように、爪部５６が第２支持部２１Bと角部２１Ｃとの側面に圧入されることによって固定されている。 The second supported portion 52 of the second terminal member 5 extends in parallel with the rear wall 22 r of the cover 22, and the second elastic piece 54 extends along the insertion direction of the thin insert 7. The bent portion 53 is bent by approximately 90 degrees and connects the second supported portion 52 and the second elastic piece 54. Further, the bent portion 53 is surrounded by a corner portion 21C (elastic deformation allowing portion) extending from the second support portion 21B toward the bent portion 53 via a gap. The corner portions 21 </ b> C are a pair of projecting portions projecting upward from the base 21, and the inner walls of the pair of projecting portions have a shape that matches the shape of the bent portion 53. The pair of protruding portions of the corner portion 21 </ b> C face each other with a gap larger than the movable range of the bent portion 53 so as to allow elastic deformation of the second elastic piece 54.
Although the second terminal member 5 is supported by the second support member 21B, the claw portion 56 and the second support portion 21B are arranged so as not to be detached from the substrate 6 even when a load is applied to the second terminal member 5. It is fixed by being press-fitted into the side surface with the corner portion 21C.

なお、第１弾性片４３及び第２弾性片５４の挿入空間の外側への変位を許容するように、基体２１には第１弾性片４３と第２弾性片５４の外側に側壁が設けられていない。また、同様の理由で、カバー２２にもこの位置に対応する箇所に開口２２ｏが設けられている。   The base 21 is provided with side walls on the outside of the first elastic piece 43 and the second elastic piece 54 so as to allow displacement of the first elastic piece 43 and the second elastic piece 54 to the outside of the insertion space. Absent. For the same reason, the cover 22 is also provided with an opening 22o at a location corresponding to this position.

次に、図３，４を参照して第１端子部材４，第２端子部材５の動作について説明する。図３は薄型挿入体７が薄型コネクタ１に挿入されていない状態、図４は薄型挿入体７が薄型コネクタ１に挿入された状態を示す平面図である。尚、図３，４はカバー２２を取り外した状態を図示している。   Next, the operation of the first terminal member 4 and the second terminal member 5 will be described with reference to FIGS. FIG. 3 is a plan view showing a state where the thin insert 7 is not inserted into the thin connector 1, and FIG. 4 is a plan view showing a state where the thin insert 7 is inserted into the thin connector 1. 3 and 4 illustrate a state where the cover 22 is removed.

薄型挿入体７が挿入空間に挿入されていない状態では、図３の如く、第１端子部材４と第２端子部材５は互いに離間しており、電気的な接続は確立されていない。
図４の如く薄型挿入体７が挿入空間に挿入されると、まず薄型挿入体７は第１弾性片４３に接触し、第１弾性片４３が弾性変形して外側に変位する。第１弾性片４３が変位すると、第１弾性片４３の外側に位置する第２弾性片５４も第１弾性片４３に押圧されて外側に弾性変形する。このように、薄型挿入体７が薄型コネクタ１に挿入されて、第１弾性片４３が第２弾性片５４と接触すると、両者の間が電気的に接続されて導通状態となる。図示しない外部の検出回路が、第１弾性片４３が第２弾性片５４との間の導通を検出して、薄型挿入体７が薄型コネクタ１に挿入されたことを検出する。 In a state where the thin insert 7 is not inserted into the insertion space, the first terminal member 4 and the second terminal member 5 are separated from each other as shown in FIG. 3, and electrical connection is not established.
When the thin insert 7 is inserted into the insertion space as shown in FIG. 4, the thin insert 7 first comes into contact with the first elastic piece 43, and the first elastic piece 43 is elastically deformed and displaced outward. When the first elastic piece 43 is displaced, the second elastic piece 54 positioned outside the first elastic piece 43 is also pressed by the first elastic piece 43 and elastically deformed outward. As described above, when the thin insert 7 is inserted into the thin connector 1 and the first elastic piece 43 comes into contact with the second elastic piece 54, the two are electrically connected and become conductive. An external detection circuit (not shown) detects that the first elastic piece 43 is electrically connected to the second elastic piece 54 and detects that the thin insert 7 is inserted into the thin connector 1.

この時、角部２１Ｃや開口２２ｏ（図１参照）が第２弾性片５４の可動ストロークを確保しているので、第２弾性片５４が弾性変形してもハウジング２等に接触することがない。したがって、第２弾性片５４が変形してもハウジング２等から外力が負荷されることがなく、第２弾性片５４は第１弾性片４３の弾性変形に伴って柔軟に弾性変形することにより、挿入体７の挿入に伴って過剰な圧力が第２弾性片５４に負荷されることがない。
なお、薄型挿入体７が完全に挿入空間に挿入されると、薄型挿入体７は第１端子部材４の当接部４４と接触し、当接部４４と第２弾性片５４が弾性接触した状態が保たれる。この状態でも当接部４４、第１弾性片４３、第２弾性片５４がそれぞれ適度に弾性変形することにより、過大な圧力が第１端子部材４と第２端子部材５に負荷されることがない。
以上のように、薄型挿入体７がハウジング２に挿入されても、第１端子部材４と第２端子部材５に過大な圧力が負荷されることがないので、疲労寿命の長い検出機構を備えた薄型コネクタ１を実現できる。 At this time, since the corner portion 21C and the opening 22o (see FIG. 1) secure the movable stroke of the second elastic piece 54, even if the second elastic piece 54 is elastically deformed, it does not contact the housing 2 or the like. . Therefore, even if the second elastic piece 54 is deformed, no external force is applied from the housing 2 or the like, and the second elastic piece 54 is elastically deformed flexibly along with the elastic deformation of the first elastic piece 43. An excessive pressure is not applied to the second elastic piece 54 with the insertion of the insert 7.
When the thin insert 7 is completely inserted into the insertion space, the thin insert 7 comes into contact with the contact portion 44 of the first terminal member 4, and the contact portion 44 and the second elastic piece 54 come into elastic contact. State is maintained. Even in this state, the contact portion 44, the first elastic piece 43, and the second elastic piece 54 are appropriately elastically deformed, so that excessive pressure may be applied to the first terminal member 4 and the second terminal member 5. Absent.
As described above, even when the thin insert 7 is inserted into the housing 2, an excessive pressure is not applied to the first terminal member 4 and the second terminal member 5, and thus a detection mechanism with a long fatigue life is provided. A thin connector 1 can be realized.

上述の薄型コネクタ１を基板６の表面に実装する時には、コネクタ端子部材３の外部接続用端子３２と、第１端子部材４へ給電するための第１端子部４１と、第２端子部材５へ給電するための第２端子部５１とを基板６へはんだ付けする。はんだ付けを、例えばはんだリフロー法を用いてする場合は、基板６上にペーストされたはんだが外部接続用端子３２、第１端子部４１、第２端子部５１を上って固着し、薄型コネクタ１が基板６上に固定されることになる。この時、必要以上のはんだが第１端子部４１，５１を上ってしまうことがある。このはんだ上がりを防止するために、図２に示したように、本発明では第２端子部材５の第２端子部５１と第２被支持部５２との間に断面積減少部５５が設けられている。   When the above-described thin connector 1 is mounted on the surface of the substrate 6, the external connection terminal 32 of the connector terminal member 3, the first terminal portion 41 for supplying power to the first terminal member 4, and the second terminal member 5. The second terminal portion 51 for supplying power is soldered to the substrate 6. When soldering is performed using, for example, a solder reflow method, the solder pasted on the substrate 6 is fixed on the external connection terminal 32, the first terminal portion 41, and the second terminal portion 51. 1 is fixed on the substrate 6. At this time, more than necessary solder may go up the first terminal portions 41 and 51. In order to prevent the solder from rising, as shown in FIG. 2, in the present invention, a cross-sectional area reduction portion 55 is provided between the second terminal portion 51 and the second supported portion 52 of the second terminal member 5. ing.

本実施の形態においては、図２に示すように屈曲部５３にはんだが付着してしまうことを防止するために、第２端子部材５の第２端子部５１と第２被支持部５２との間に断面積減少部として開口５５が設けられている。はんだ付けの際は、第２端子部５１の先端から供給される熱が第２被支持部５２を介して屈曲部５３へと供給される。このとき、この第２端子部５１と第２被支持部５２との間に、両者の間の断面積を減少させる開口５５が設けられているので、はんだ付けの際の第２端子部５１から屈曲部５３への熱伝導が抑制され、屈曲部５３の加熱が抑制される。   In the present embodiment, as shown in FIG. 2, in order to prevent the solder from adhering to the bent portion 53, the second terminal portion 51 of the second terminal member 5 and the second supported portion 52 An opening 55 is provided as a cross-sectional area reducing portion therebetween. During soldering, the heat supplied from the tip of the second terminal portion 51 is supplied to the bent portion 53 via the second supported portion 52. At this time, since the opening 55 for reducing the cross-sectional area between the second terminal portion 51 and the second supported portion 52 is provided, from the second terminal portion 51 at the time of soldering Heat conduction to the bent portion 53 is suppressed, and heating of the bent portion 53 is suppressed.

一般にはんだ付け工程においては、はんだの融点以上に加熱された領域にはんだが広がるので、はんだを付着させたくない領域ははんだの融点以上に加熱しないことが好ましい。本発明によれば、開口５５が第２端子部５１側から屈曲部５３への熱伝導を抑制しているので、第２端子部５１をはんだ付けに十分な温度に加熱しても、屈曲部５３がはんだ付けに十分な温度に到達しにくくなる。   In general, in the soldering process, since solder spreads in a region heated above the melting point of the solder, it is preferable not to heat the region where the solder is not desired to be heated above the melting point of the solder. According to the present invention, since the opening 55 suppresses heat conduction from the second terminal portion 51 side to the bent portion 53, the bent portion can be obtained even if the second terminal portion 51 is heated to a temperature sufficient for soldering. 53 becomes difficult to reach a temperature sufficient for soldering.

また、開口５５が溶融して上がってきたはんだを貯留することで、はんだが開口５５から更に上に上ることを抑制するので、はんだが第２被支持部を伝って屈曲部５３にまで到達することをより効果的に抑制できる。このように、本発明によれば極めて簡単な構造ではんだ上がりを効果的にかつ安価に防止することができる。   Further, by storing the solder that has been melted and raised in the opening 55, it is possible to prevent the solder from further rising from the opening 55, so that the solder reaches the bent portion 53 through the second supported portion. This can be suppressed more effectively. As described above, according to the present invention, it is possible to effectively prevent the solder from rising with a very simple structure.

さらに、本実施の形態では、第２支持部２１Ｂの外側は、第２端子部材５の第２端子部５１を覆う端子被覆部としても機能している。この第２支持部２１Ｂには、前記第２端子部材５が露出する溝２１ｇが設けられている。この溝２１ｇによって、はんだの上がる方向を任意の方向に誘導できる。さらにこの溝２１ｇの中に開口５５を設けたので、溝２１ｇを伝って上がってきたはんだを確実に開口５５に貯留することができる。本実施の形態においては第２端子部５１から第２被支持部５２に向かって溝２１ｇを形成しているので、第２端子部５１と第２被支持部５２との間の開口５５に確実にはんだを誘導することができ、屈曲部５３へのはんだ上がりを確実に防止することができる。   Furthermore, in the present embodiment, the outside of the second support portion 21 </ b> B also functions as a terminal covering portion that covers the second terminal portion 51 of the second terminal member 5. The second support portion 21B is provided with a groove 21g through which the second terminal member 5 is exposed. By this groove 21g, the direction in which the solder goes up can be guided in an arbitrary direction. Further, since the opening 55 is provided in the groove 21g, it is possible to reliably store the solder that has risen through the groove 21g in the opening 55. In the present embodiment, since the groove 21g is formed from the second terminal portion 51 toward the second supported portion 52, the opening 55 between the second terminal portion 51 and the second supported portion 52 is surely provided. Thus, solder can be guided to the bent portion 53 and the solder can be reliably prevented from rising up.

上述の断面積減少部５５の作用を詳細に説明するために、はんだ上がりの現象について図５を用いて説明する。図５は、断面積減少部５５が設けられていない参考例の薄型コネクタの要部拡大図である。参考例にかかる薄型コネクタは、第２端子部材１０５に断面積減少部が設けられていない点以外は上述の実施の形態と同様なので、同様の部材については同様の符号を付してその説明は省略する。   In order to explain the operation of the cross-sectional area reducing portion 55 in detail, the phenomenon of solder rise will be described with reference to FIG. FIG. 5 is an enlarged view of a main part of a thin connector of a reference example in which the cross-sectional area reducing portion 55 is not provided. The thin connector according to the reference example is the same as that of the above-described embodiment except that the second terminal member 105 is not provided with the cross-sectional area reduction portion. Omitted.

第２端子部材１０５を基板６にはんだ付けする際、必要以上のはんだが第２端子部材１０５の第２端子部１５１を上ってしまうと、第２端子部１５１は第２被支持部１５２や屈曲部１５３の近くに配置されているため、はんだが第２被支持部５２を伝って屈曲部１５３に付着する虞がある。特に、第２支持部２１Ｂから角部２１Ｃが連続し、また、角部２１Ｃと第２端子部材１０５との間に隙間があるため、第２端子部１５１から上ってきたはんだがこの隙間を伝って角部２１Ｃの間に侵入しやすい。はんだが第２端子部１５１を上って屈曲部１５３と角部２１Ｃとの間に侵入すると、本来設定されていた第２被支持部１５２から延びる第２弾性片１５４の長さ（換言すれば、カンチレバーの自由端長さ）が短くなってしまう。   When the second terminal member 105 is soldered to the substrate 6, if more than necessary solder goes up the second terminal portion 151 of the second terminal member 105, the second terminal portion 151 becomes the second supported portion 152 or Since it is disposed near the bent portion 153, the solder may adhere to the bent portion 153 along the second supported portion 52. In particular, since the corner portion 21C is continuous from the second support portion 21B and there is a gap between the corner portion 21C and the second terminal member 105, the solder rising from the second terminal portion 151 passes through this gap. It is easy to penetrate between the corner portions 21C. When the solder goes up the second terminal portion 151 and enters between the bent portion 153 and the corner portion 21C, the length of the second elastic piece 154 extending from the originally set second supported portion 152 (in other words, , The free end length of the cantilever) will be shortened.

第２弾性片１５４の長さが短くなると、第２弾性片１５４のばね定数が大きくなる。すると、第２弾性片１５４が同じ距離だけ変位したとしても、はんだが屈曲部１５３に付着した場合は、はんだが屈曲部１５３に付着しない場合よりも、第２弾性片１５４に大きな圧力が発生することになる。特に、高さ寸法が小さい薄型コネクタでは、第２端子部材１０５の厚みや幅が小さいため、長さ寸法が微少量変化した時でもばね定数に与える影響が大きくなる。したがって、薄型挿入体７を挿抜する度に、本来想定していた圧力よりも大きな圧力が第２弾性片１５４に負荷されることになり、第２端子部材１０５の疲労寿命が設計した値よりも著しく短くなってしまう。   When the length of the second elastic piece 154 is shortened, the spring constant of the second elastic piece 154 is increased. Then, even if the second elastic piece 154 is displaced by the same distance, when the solder adheres to the bent portion 153, a larger pressure is generated in the second elastic piece 154 than when the solder does not adhere to the bent portion 153. It will be. In particular, in a thin connector having a small height dimension, since the thickness and width of the second terminal member 105 are small, the influence on the spring constant is increased even when the length dimension is slightly changed. Therefore, each time the thin insertion body 7 is inserted / removed, a pressure larger than originally assumed is applied to the second elastic piece 154, and the fatigue life of the second terminal member 105 is larger than the designed value. It will be significantly shorter.

上述の断面積減少部５５の効果を図６，７で示す。図６，７は本発明にかかる薄型コネクタと参考例にかかる薄型コネクタのはんだの付着状態を示す模式図であり、薄型コネクタを基板６にはんだ付けした後の第２端子部材５，１０５を示している。図６，７において符号８の斜線部ははんだを示す。   The effects of the above-described cross-sectional area reducing portion 55 are shown in FIGS. FIGS. 6 and 7 are schematic views showing the state of solder attachment of the thin connector according to the present invention and the thin connector according to the reference example, and show the second terminal members 5 and 105 after the thin connector is soldered to the substrate 6. ing. 6 and 7, the hatched portion with reference numeral 8 indicates solder.

図６のように断面積減少部５５を有する本発明に係る薄型コネクタにおいては、断面積減少部５５が端子部５１から被支持部５２への熱伝達を抑制するので、はんだ８は断面積減少部５５から被支持部５２および屈曲部５３側まで到達することがない。しかし、図７のように断面積減少部５５が設けられていない参考例に係る薄型コネクタにおいては、はんだ８は被支持部１５２や屈曲部１５３まで到達してしまい、第２端子部材１０５が早期に破損してしまう虞がある。   In the thin connector according to the present invention having the cross-sectional area reduction portion 55 as shown in FIG. 6, the cross-sectional area reduction portion 55 suppresses heat transfer from the terminal portion 51 to the supported portion 52. The portion 55 does not reach the supported portion 52 and the bent portion 53 side. However, in the thin connector according to the reference example in which the cross-sectional area reducing portion 55 is not provided as shown in FIG. 7, the solder 8 reaches the supported portion 152 and the bent portion 153, and the second terminal member 105 becomes early. May be damaged.

以上のように、図６の如く第２端子部５１と第２被支持部５２との間に断面積減少部５５を設ければ、簡単な構造で効果的に屈曲部５３へのはんだ上がりを防止でき、第２端子部材５の早期の破損を防止できる。   As described above, if the cross-sectional area reducing portion 55 is provided between the second terminal portion 51 and the second supported portion 52 as shown in FIG. 6, the solder can be effectively lifted to the bent portion 53 with a simple structure. This can prevent the early breakage of the second terminal member 5.

なお、上述の実施の形態では第２端子部材５のみにはんだ上がり防止のための開口５５を設ける構成を挙げて説明したが、第１端子部材４のみ、あるいは第１端子部材４と第２端子部材５の両方に開口５５を設けてもよいことはもちろんである。   In the above-described embodiment, the configuration in which only the second terminal member 5 is provided with the opening 55 for preventing solder rise has been described. However, only the first terminal member 4 or the first terminal member 4 and the second terminal are provided. Of course, the openings 55 may be provided in both of the members 5.

また、上述の実施の形態では第１弾性片４３、第２弾性片５４とは薄型挿入体７の側面に対して弾性変形可能な例を示したが、本発明はこれに限られない。例えば第１弾性片４３、第２弾性片５４が薄型挿入体７の厚み方向に変位可能に構成してもよいことは明らかである。   In the above-described embodiment, the first elastic piece 43 and the second elastic piece 54 are shown as being elastically deformable with respect to the side surface of the thin insert 7, but the present invention is not limited to this. For example, it is obvious that the first elastic piece 43 and the second elastic piece 54 may be configured to be displaceable in the thickness direction of the thin insert 7.

さらに、上述の実施の形態では、薄型挿入体７が挿入されたときに第１端子部材４と第２端子部材５との間が導通し、薄型挿入体７が挿入されない時には両者の間が非導通になる例を説明したが、本発明はこれに限られない。薄型挿入体７が挿入されたときに非導通とし、挿入体７が挿入されない時に両者が導通するように構成してもよいことは明らかである。   Further, in the above-described embodiment, when the thin insert 7 is inserted, the first terminal member 4 and the second terminal member 5 are electrically connected, and when the thin insert 7 is not inserted, there is no gap between the two. Although the example which becomes conduction was demonstrated, this invention is not limited to this. It is obvious that the thin insertion body 7 may be configured to be non-conductive when the insertion body 7 is inserted and to be conductive when the insertion body 7 is not inserted.

さらに、上述の実施の形態では、断面積減少部を開口５５とする例を説明したが、第２端子部５１と第２被支持部５２との間に幅方向（基板６と平行な方向）の少なくとも一方を切り欠いて形成した切欠であってもよい。また、上述の実施の形態では断面積減少部５５を単一の開口として説明したが、開口を複数設けても良いことは明らかである。上述のように、断面積減少部５５は第２端子部５１側から第２被支持部５２への熱伝導を抑制するものであれば十分であって、その形状は限定されない。   Furthermore, in the above-described embodiment, the example in which the cross-sectional area reducing portion is the opening 55 has been described. However, the width direction (direction parallel to the substrate 6) is between the second terminal portion 51 and the second supported portion 52. It may be a notch formed by notching at least one of the above. In the above-described embodiment, the cross-sectional area reducing portion 55 has been described as a single opening. However, it is obvious that a plurality of openings may be provided. As described above, the cross-sectional area reduction portion 55 is sufficient as long as it suppresses heat conduction from the second terminal portion 51 side to the second supported portion 52, and the shape thereof is not limited.

以上、本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。   While the invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
